Help request: How can I "purge" a document to remove corruption/conflict/whatever it is causing the file to misbehave.
Symptoms: In model space the scroll bars are locked on centre of drawing extents. Mouse wheel zoom is fixed on that centre point whereas it used to zoom on the cursor. Other view commands work.
Tried: Resetting profile (done that several times before!) resetting every zoom command I could find in the multitude of menu entries for settings, changing Logitech M705 mouse controls. Then, I tried an old version of the same drawing (past corrupted files = caution) and "Lo, Behold", they zoom as before.
Conclusion: About my 5th corrupted file in 2 years and two or three hours to correct. Very
