well the latest version kept getting stuck so I reverted to V0.2.3 which was the only one I had in my bin. Its running very well actually.
My point though was that it still only uses a small amount of memory even when I start it with your suggestion above.
I did test the latest version like that but it carried on stalling while downloading the blockchain.
Its now using 34mb and running like a charm.

Anyway, Nxt looks like it has a lot of potential. So, hats off to the developer.
I think the decentralised exchange will be challenging. Is the developer confident he/she can actually do this?

I noticed that my local copy of Nxt runs much more stable than one on VPS (88.198.210.245). I suspect this is because my local computer has much more memory available. If ur node has more than 256 Mb RAM then use the following command to launch Nxt:
-Xms and -Xmx make Java VM to use more memory. Notice there is no space between "-Xms" and "512m". U can set other values instead of 512 and 1024.
Code:
java -Xms512m -Xmx1024m -cp Nxt.zip Nxt IP_ADDRESS

Mine is only using 76mb
I agree. What's wrong with keeping it simple and using NXT?
Standard (http://en.wikipedia.org/wiki/ISO_4217) forces usage of "X??" notation AFAIK.
Not all standards need to be followed. Does bitcoin follow this standard?
It lists the version number when you start the client

I had no problem in previous versions, but in this new 2.9 I can't catch new blocks easily.
When it's open nothing changes in block height, just shows block catching, but no number change even after 30 mins waiting.
Only after I exit and re-open the browser and re-login into my account again, it shows some max. 50 to 100 block height change.
I am waiting to catch up the blockchain to send some tx. As I tried several times, it says: please wait until the blockchain become loaded..
Dunno how long it would take

How do you check the version number?

Is it possible to also look at a Nxt address to see transactions, or is it only possible with blocks?
Only via blockchain parser. I published the code of 1st Nxt Slot Machine that parses the whole chain. Someone could add extra functionality on top of that.
Cool, thanks!
Please reference the Next API thread too. Any ETA on when the new client functionality comes out? I think the earlier version had messaging, but I did not see that in the last TEST client. Will it be there? I had some ideas for using that interesting feature.
BTW, is it NXT or XNT? Guess we go with NXT.

Yes, Nxt will have a messaging feature too.
It's called Nxt (pronunciation "Next"), but the three letter currency code is XNT.
This is a poor decision to have it XNT as a ticker code; you're just looking to piss off dyslexics.

Any solution to this?

It's not a problem. Someone announced an incorrect IP address (I see 88.198.210.2455 for example) and client tries to connect to it.
Those messages should not be logged as errors, but be logged as debug and thus hidden from view under normal conditions.

The phraze is the key to your account.
- agree 100%. And there is no "wallet" in Nxt (unlike in bitcoin).
The bitcoin wallet is not really a wallet, it's a bunch of private and public keys (a keychain), just like passwords/passphrazes.
Is it possible to also look at a Nxt address to see transactions, or is it only possible with blocks?

this phraze WILL BE YOUR WALLET. There is no user name, and no wallet file.
- there is no WALLET in Nxt as well. This word "WALLET" may lead to misunderstanding. Your phrase is your ACCOUNT.A bitcoin wallet is a bunch of encryption keys, not far off from your Nxt phraze, which is also a key. Your account number is your account, not your phraze. If you want to send someone Nxt you use the account number, not the phraze. The phraze is the key to your account.
