if I try to rename nodes in the object tree, I often get the MessageBox(of death)
Fatal error: Unknown reason (System error code: -2118952392) Saving dump file ...
Can someone tell me what causes this error and how I can avoid it?
This is almost impossible to track down, when it's not reproducable.
As dump file creation is obviously enabled, you may also enable the dump-file diagnostic tool in eMPowerDoctor.
It will write a log-table, that keeps info about each crash.
You may then open an IR in GTAC and upload your dump-file.
Maybe it will tell the cause of the crash.
