Windows 7: windows 7 + farmville game issue

Hi all, i am having this strange issue in windows 7. I am not able to delete any farm land farmville game if i play it in any browser running on windows 7. There are some other issues with farmville game also. I have tried all the major browsers like IE 8, Firefox, Google Chrome, Opera all recent versions.
But if i open and play the same game in windows XP, then i can play it perfectly well. Is there any problem with flash in windows 7? i have installed the most recent version of flash player also.



Windows 7 32 bit.
IE 8
FireFox 3.6.
Opera 10.50
google chrome 4.x.x

Please help me . Thank you.

Checked to see any restrictions on the flash?. IE, your browser settings?

Did you try flash 10.1 prerelease :Adobe Labs - Downloads: Flash Player 10.1

You need java and flash for facebook. Update both.

i did a clean re-install of windows 7. i use the latest java and flash stuff , so no problem on that count. What i found out is in my opinion the culprit was kaspersky internet security in which i enabled the Anti-Banner thing of Online activity. After i disabled that thing, i can use all the browser to delete any farm land from farmville. But still i am not sure of it. Anyway it solved the problem.
