is Coin Control enabled? GUI freezes whenever i click it.
It is, and it shouldn't trigger a freeze. Post your logs for investigation.
I too have been having this issue with 0.96.1 and 0.96.1.2 RC2. I have some further information regarding the problem, and my armory log, as well. First, I start with a new install of 0.96.1.2 RC2 with an empty ~/.armory directory. I import my online watching only wallet from a digital backup. Armory builds it's database, scans it, scans my wallet, etc. After all this, Armory starts up fine and everything works. Before I do anything, I shut Armory down and back up the entire ~/.armory directory. I start Armory back up, the coin control button/gui works and I use it to create an unsigned transaction. After I have finished creating the unsigned transaction is when the problem starts. Now, if I open the main "Send Bitcoins" menu, and then click the button for "Coin Control", armory becomes unresponsive. I can still move the "Send Bitcoins" window, and the main armory window, but nothing inside the windows will respond to anything, and they will not close/quit, so I have to kill armory-qt and ArmoryDB from the system monitor. After I kill them, if I start up Armory again, the main window and "Send Bitcoins" menu will work but it again freezes when clicking "Coin Control". At this point, however, I can broadcast my transaction after signing it offline, and it will broadcast and confirm. In order to use my wallet again, I shutdown Armory, delete the ~/.armory folder, and restore it from my backup I made before creating the transaction. Now if I start armory up again, it will pick up my new transaction after scanning for a few seconds, and display it with the rest of my transactions. I can now successfully open the coin control menu again. I have included a link to my log file which I uploaded to my github account. My log file contained some information about my transaction, so these parts, and any other parts I thought might be sensitive information, I replaced with X's.
