In PB 6.04 and PB 6.10 (all Beta versions) the width of the IDE sometimes increases without the user changing the width of the IDE. To reproduce the bug (which only occurs in Linux!):
- Open IDE
- Change the IDE's width to display about 80 characters
- Type "Mess" and then <Tab>
The width of the IDE is increased without any user interaction! And afterwards it isn't possible anymore to change the IDE's width with the mouse. You have to click onto the run icon or to close and reopen the IDE to be able to change the IDE's width.
This bug didn't occur in PB 5.73 and prior versions and in PB 6.00 to 6.02. Unfortunately I wasn't able to test PB 6.03 because PB 6.03 is still not included in the "museum".
