777 VC small error

Hi guys. I have several 777 aircraft downloaded for FSX and they seem to work well... except one small thing. When using autopilot and changing the numeric values (altitude, speed, heading etc.) my cursor flickers and is a pain to change the values. has anyone else had this problem and is there a fix?

Thanks in advance

See if this works.
Disable Tooltips in the Settings/Display/Aircraft.

No didn't work. The cockpit also seems to go transparent now and again and the auto pilot doesn't actually work when switched on

If the cockpit goes transparent as you say then the slides are set too high for your computer (especially the video card).
I would lower some of the slides, autogen, clouds, and shut off shadows and AI.
See if this helps..
