Does the file transfer complete or are you unable to transfer the file at all? Despite the inconvenience, yes, I can transfer the files.
Once the file transfer is complete do you regain control? Yes, I can!
Does this happen with any other computers or just this one?
I'm still not sure, but on some it happens that the application closes.
Important info I forgot to mention. This only happens when transferring files from the client workstation to the Support Agent. If I transfer from my machine to the client's, everything happens normally.
