Strange Behaviour for Menu Items

[BogdanF]

hello,
i have ms windows vista home premium x64 sp1.
sometimes when i start my windows session, the right menu items are blinking
when i am hovering them with my mouse-cursor. ( even tabs - task manager )

to have the normal "settings" i have to log off and log-on again or to
restart my machine.
this is happening in a random way...

i don't know why...
i run from cmd - sfc /scannow and the system is saying that my "os
integrity" is ok.

can you help me with this "issue" ? how can i "kill" it?

thank you!

and it will be solved even when I change my THEME to "Windows Classic" and
make it back to aero...

Could be this a bug in my Aero GUI theme package? How can I resolve it?
