I have experienced this in the past, but it has been occurring mush more frequently. I use my scroll button to pan & lately, 2 things occur.
I get the "FATAL ERROR: Unhandled Access Violation Writing 0x541fee4 Exception at 332bfee0h" error. Sometimes a recover file is craeted, sometimes, not.
or
CAD just shutsdown.
I have recovered & audited all files in the drawing & no errors found. I did a search in autodesk website & was unsuccessful finding this error. Anybody else experience this?
