Run-time error '440'

[undupit]

We have done another test with AllDup 4.3.12 Beta on a fresh installed Win10 Pro v1903 PC and everythings runs without any errors...

I get the same error, when doing a large compare (not if I cut the compare in small pieces), but after error 380:

Using 4.5.38 PE.

To be clear, you're getting both 380's & 440's ?
And here you're using .38 & in the other thread .64 ?

I can't remember.
Error 440 is not reproducible: sometimes it gives the error, sometimes it doesn't.
For error 'mTScrollContainer: Run-time error '440': Automation error', in AllDup 4.5.38 PE, Win10, GPT says:
Examples of effective fixes:
# Ensure all mTScrollContainer access happens on the UI thread, and nowhere else.
# Defer UI updates (queue them, throttle them, or batch them) instead of calling into the control during the comparison loop.
# Separate work and UI completely: do the comparisons first, then update the UI afterward.

I don't know if GPT is correct. I know for a fact that it's often wrong.
