TeraCopy : error when waiting too long?

I used TC to copy 2 used/opened files from a folder of a program, so tc had to "wait" for it to be closed.

This is going well if it does not last too long.

Today it lasted ca. 5 hours until closing the app and to let these files "free" to copy.

But TC did not work :(

It seemd to bee freezed, i could not stop or pause or restart any action. o_O

Also the repeating to copy per context menue does not work, but the list of jobs has been updated.

So i had to kill the process.

This seems to be an error.

Is there no TC protocol to send it to you to fix it?
