Thank you for your feedback regarding this issue.
CROATCore only saves recently used wallets if the user properly exits the application [i.e., uses the close button and waits for the application to completely shut down which may take up to a minute].
Once the application is shutdown correctly, it saves the recently used wallets in a file called: "recentw.cro".
If, for some reason, the folder where CROATCore attempts to save the file becomes read-only, the app will be unable to save the file thus no recently used wallets would be visible once CROATCore would be restarted.
Also, if for any reason, the file is removed from that folder, CROATCore would be unable to load the recently used wallets.
As such, on the machines where you are not seeing your recently used wallets, could you please let us know if the file called "recentw.cro" exists ?
In Windows, the file is saved in the same folder as your application.
The same explanation applies for pool settings as well which are saved in a file called "pref.cro".
In conclusion, it would be interesting to find out if these files exist in your application folder, first. Again, these files are generated only when CROATCore is properly shut down.
Regarding the wait for synchronizing with the daemon, what version of the app are you using ?
Indeed, current version do not allow wallet operations and/or mining until the CROATCore is fully synchronized with the network. However, the latest version should minimize in-app daemon synchronization waits.
Sometimes new data arrives and CROATCore makes sure that its daemon is synchronized with the network before allowing operations and that is why you are seeing the synchronization with daemon message; no need to reinstall the application, this is expected behavior at this point in time.
You may also see this error message if you initially enter an incorrect password and after entering the right one, you may have to wait for a while until everything is synched again.
We are planning on soon releasing a new version which will allow you to start mining right away without having to wait for network synch.
Thanks again for your feedback.
We are looking forward to hearing back from you about the "recentw.cro" and "pref.cro" files [whether they exist in the app folder on the machines where you do not see your recently used wallets and pool settings].
I checked, there is this file in the program folder - recentw.cro
I think it is worthwhile to think about the intermediate preservation of this file, because sometimes the farm hangs and leaves in the blue screen! then it reboots, it turns out that the program was not saved properly and the pool data was not saved.
you can configure the saving of the file once per hour or at a different interval, you can save after clicking on start mining.
what happened to the difficulty in the last 2 days? every day it increases by 2 times, and the amount of coins mined falls 2 times.
I noticed that if you run each farm on a separate wallet, and not all on 1, then the income is higher.
