Can other applications mess up Copy/Paste in Word VBA script?

[diracsbracket]

Hi.
I have a script that extracts tables from a series of documents and which takes a rather long time. The tables are extracted via .Copy and .PasteSpecial commands, and thus the clipboard is being used.

However, once in a while, for no apparent reason, the script hangs and needs to be restarted, after which it works fine on exactly the same docs.

Is it possible for other applications using the clipboard to mess each other up? For example, if I copy something in another application, will that mess up the clipboard contents as expected by my VBA script?



Thanks~
