I'm still seeing this glitch, sometimes a few times a day (leading to lost development time, since I now compile twice with each change to be sure the changes are 'caught'), anyone find a solution yet?
We have been unable to observe the problem but we did make some changes that might circumvent the problem. You can try the experimental v1.5.2 release if you'd like to. Just extract the .exe file to the IDE subdirectory of the ZBasic installation directory. You might want to save off or rename the existing ZBasicIDE.exe before doing so.
