Run script not working

[closer]

Hi,
we have big project with many own VBScripts.
Until today all of them works excellent, but from this morning we have problem on some computers with Windows 7.
When I push the "Run script" button, it disables for moment (less than 1 sec), then back to "enabled" state and .... nothing happend. No script was running.
Doesn't  metter what script we want to use, even demo scripts not working

Please Help
