The Pause/Resume logic with the buttons needs a modern update. If you never pause the script using the menu button(s) then it wouldn't affect it.
I would be curious for a description of "it crashes":
1) The uo client becomes unresponsive?
2) the uo client terminates and goes away completely?
The first one is what Crisis describes for a fix (close client, close Easyuo, restart both; sometimes I have to resort to rebooting my PC to get that to cleanly startup).
The second one happens when there is a conflict with dragging an item while moving... there may be other situations where that could happen, but that is the most common one I have witnessed. This fix is to stop moving and dragging items at the same time.
If it is me dragging items or clicking to move... well, I blame myself. If it is a script dragging/moving items... then eliminating that conflict is important.
I thought I was very clever recently and while a script was running, I decided to sum up the uses left on my backpack full of instruments while I was bard training. My client crashed and went away similar to the move/drag result. This is still my fault, but I offer it as a potential issue. Both scripts were doing a finditem and that is a bad thing in the same client... but in different scripts. Are you running a second script that is on that account that could interfere with the first script's operation?
