BUG: Editor crashes when monitor turned off

[roltemurto]

Hello again WillLem,

Sorry for bombarding the forum board lately, but I got a new bug report.
Below I am attaching the .NET Framework error pop-up. The log file doesn't have anything up to date.
This happened after I turned my monitor off for an hour (at least this is what I am suspecting of what caused it).
When I turned it back on these errors were popped up;

Instead of this dialog box, JIT debugging would be invoked

************** JIT Debugging **************
To enable JIT debugging, the jitDebugging value must be set in the
system.windows.forms section of the application's or machine's (machine.config)
.config file. The application must also be compiled with debugging
enabled.

For example:
<configuration> <system.windows.forms jitDebugging="true" /> </configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than being handled in this dialog box.
Luckily the editor DID allow me to save the map before exiting.
The reason I'm suspecting the monitor is due to the fact that I am using displayport for connection and I believe this connection causes resolution change during turn off and wake up.

[WillLem]

It appears to have been triggered by the form resizing. Your instincts are likely correct: if the resolution change occurs on wake, that could trigger a form resize.

Not sure exactly why the exception occurred though. Maybe more resolution-specific guards need to be in place.

Good to know that no data was lost, that's fortunate.
