Intermitten Blackouts (???)

[Mothball]

I have had this malfunction ever since I have started using FSX. I'm flying along just fine (usually the C172), then I decide that I want to check, for instance, my Garmin (it could be any icon or just changing views), so I click the GPS icon on the (2 D) panel, the GPS screen comes up just fine, and now I have a perfect looking panel and a perfect looking GPS screen. Now here's where the problem is, my outside view is totally blacked out. I can use the hat to look out to the sides and back just fine, but my front view is gone. I have found that if I cycle through the different views several times my front view comes back eventually, but then, when I look to my right and left (in any screen or view) I have some fairly big black squares where my lights should be flashing. This can happen anywhere between 5 - 20 minutes into the flight and usually when I am beginning a decent for a TNG/landing. Anybody else having this malfuction? Anybody know how to clear it? Thanx in advance. Semper Fi, Dave

I don't have the complete spec sheet on my pc right now, but I do know I have a ATI Radeon X 1900 GT with 4 G's  of memory on Vista 32bit. I post the rest of the spec sheet when I find it.

Bump. Changed from an ATI Radeon 1900 GT to an Nvidia 8500 GT that I found on sale for $88 at Best Buy. It seemed to make pretty good difference especially in FS9. It also made good bit of difference in FSX, but now when I go to click on the icons I get a white screen for 2 seconds, then it turns black for two seconds and then I get my cockpit back and it allows me to get whatever gadget  I need to check. I get a partial black out looking out the front of the 2D panel and I still get black squares where my lights on the plane are, and now I'm getting the glide slope lights and a few of my AI traffic labels with black squares (no particular set or type of AI traffic is affected ?) while the rest are their normal red lettering about 20 mins into the "flight". Any ideas? Semper Fi, Dave

uncheck 'show cockpit tooltips' in the aircraft settings

that should get rid of the flashing screen with instruments

know FSX bug

That was it. I would have never guess that. Many thanks. Hand Salute. Semper Fi Sir, Dave
