xojo2015.4 is crashing suddenly on windows11, especially when touching controlname to view while writing code.
Are there any error messages or crash logs that may help indicate a problem. When you say it crashes suddenly do you mean that it has just started happening and has worked correctly previously? Or do you mean that it crashes when ever you do that action?
2015 is a long time ago and I’m pretty sure is 32bit. Do you need perhaps to set some compatibility flags on the application that could make it work more reliably. For example setting it to Windows 7 may perhaps work better?
For Windows 10 and 11 support, I extremely advise upgrading to 2023r4.
Since Windows XP times, dozens of APIs were deprecated in Windows, some removed over time in Vista, maybe you touched one of those incompatibility places.
Since Windows 8.1 some infos were introduced into an internalized manifest.
Many changes.
take a look at the updates windows 11 made recently, certainly one of them is causing the crash.
but yes you should really update your xojo version !
It happened again seconds ago with no message.
I got 2023r3.1 installed also but i need to use 2015 for old ones to improve for some reason.
I will test compability option .
Check the MS Event Viewer, maybe the event logged some info about the crash.
Like invalid function call, missing DLL, “Catastrophic Failure” 
etc.

So the crash is happening in the MSVCR120.dll that ships with Xojo. Perhaps a the compatibility will help?
I guess your system already contains MSVCR120.dll at Windows\System32
Rename C:\Program Files (x86)\Xojo\Xojo 2015r4\Xojo Libs\MSVC*.* to C:\Program Files (x86)\Xojo\Xojo 2015r4\Xojo Libs\MSVC*.*.old
And try again. Let’s see if the system updated ones fix it
If not, inspect the events again, for more clues, or rename them back if giving up.
