Same here, since I've changed from 5.73 to 6.11 I have multiple situations where the IDE just start hanging here and then. Even the CPU load is still low (around 8 or 12%), the IDE window doesn't react, waiting 10 or 15 minutes doesn't change anything.
Maybe there's a debugging version available to get detailed information what's going wrong.
There's no indication what triggers the issue, most of the time it is a shortcut (Ctrl+F, F5, Ctrl+Pos1 or whatever).
I do play around with PB6.11 for 10 days or so and the crash "counter" must be close to 100. So the session history (which I never saw before) has tons of confusing (Unsaved source...) entries already. Would be nice to get some sorting/filter options and more information about the file (e.g. the size in bytes because between a click on one item and the moment until the source is seen may take 5 seconds or so). A right button menu with options like "Load source into IDE..." or "Save source as..." would be fine as well.
Switched off session history three days ago and - finger crossed - no crash for now...
...will keep the setting disabled for a week or so and will post the results here.
Bad news, the IDE freezed again (session history is still disabled). I just was scrolling around and was wondering that some lines seemed to look wrongly intented. I had only some "milliseconds" before the window was shown whitened so I am not sure what lines have been shown - my impression was that they where from the collapsed procedure above the cursor.
I am using a portable installation and use identical prefererence files as for PB5.73 - same has been done with 6.00, 6.04 and 6.10 which I din't use very often but I can't remember that any IDE has been freezing before I started using 6.11.
I am also experiencing a lot of freezes since PB 6.xx. I am using the windows x64 IDE. The window stops responding and i have to kill the process. It happens at random several times a day.
Didn't test 6.20 for now, so I can't give a feedback here.
What I could see meanwhile is that the problem was not introduced with version 6.11 but earlier - actually I work with 6.04 and have to accept two or more crashs a day.
