clipboard behaviour client 2008 and win7

Hi guys,

the client 2008 and windows 7 show some weird clipboard behaviour. Try the follwoing

1. start client 2008 (SP30 - SP39)
2. copy some text into your clipboard
3. open any form (ticket, problem, change, ...)
4. doubleclick on a field label
5. paste the content of your clipboard into any field

=> the former content of your clipboard has been replaced by the name of the label from step 4.

any ideas?
