Vista - Entering Data in Flash Forms

We have an online system developed that makes use of Flash Form through a
web browser. Up until now there have been no issues, but I have changed to
VISTA OS and IE7. Now when entering data into the form I am getting
keystroke errors, where the keys are not recognized and skips over them. So
for example I type "Client is homebound" I look up and see "Clt ishm bnd".
Only is happening on my system. The XP systems using IE7 do not have this
issue. Does anyone have any ideas on what is wrong and how I can fix it?

I am on Flash Player 9 and Acrobat 8.0. Once again, the ONLY difference
between my system and the other is XP vs. VISTA.

TIA
