Windows 7: Acer Aspire 6930 win7; launch manager problems

Ive had my Aspire 6930 for about a year, i just upgraded to Windows 7, everythings going well, except for the occasional annoyance thats easily fixed....but has anyone else upgrade to 7 from vista ...if so with the drivers/applications....how can i get my launch manager to work ...its really annoying me ...mm the problem is when i change volume or something it hangs...and then doesnt work and the volume just sits there on screen not moving....and sometimes (most of the time the other touch buttons dont even work)

Pretty sure you'll find an updated LaunchManager application for Win 7 at the Acer Support site. I had exactly the same problem when going from Vista to 7 with Acer 6530 and recall fixing it this way. Good Luck.
