Windows Embedded Compact 7 and F9 Key

Hi all,

did anyone try to press F9 key on Windows Embedded Compact 7? Both on MC32N0 and MC92N0 pressing F9 cause a feedback audio. The curious thing is that after a long standby (one day or more)  the feedback audio is delayed of one or two second. In this period the terminal is freezed. With datawedge running you can't start a read until the audio beep is played. Unfortunately I've an old program that use F9 before a barcode read! The customer isn't happy to wait this period.

Anyone know if OS or terminal use F9 as shortcut for some feature?

 

Thanks in advance for any help!

 

Franco.
