These things are never just the driver or just the application but an unfortunate clash between the two, which could be caused by either one of them behaving in an unexpected way. There's no way application or game developers can test with every single driver out there, particularly ones that haven't been released yet.Having said that, given that the bug is seen with several different drivers and cards, the FSX code does seem to be the most likely target for a fix. I have the problem too and I agree it's annoying.Is it my imagination or did this problem not exist before SP1?Colin

It was happening before and after SP1.Not much of a problem as I fly only in the VC, but it is still a pain. Now as far as the drivers goes, this same problem used to cause a CTD, but one of those ATI updates took care of that problem. I guess that is what cured it.What would really be nice to have a tool tips check box for the 2D panels and another tool tips check box for the VC.

I get the same problem on my Dell D810 laptop with ATI X300 mobility 64 mb graphics card. Except it's not related to tooltips. My problem is with screen overlays (text written on the screen, popping up 2D panels) and when I change attitude quickly in large increments (like when doing a loop it flashes when the nose goes up past the horizon).I don't get this problem on my desktop 8800 GTS 640 mb graphics card system. Funny thing is, tooltips work fine on my laptop (and 8800).I feel like it is a relatively new problem, and am afraid I changed some setting somewhere, either on my graphics card or in FSX. But I've tried everything I can think of and nothing has fixed it.Thomas[a href=http://www.flyingscool.com] http://www.flyingscool.com/images/Signature.jpg [/a]I like using VC's :-)N15802 KASH '73 Piper Cherokee Challenger 180

It seems related to loading of the proper font for tooltips. Look closely to the font type when a tooltip appears, it has to be a very small font. Sometimes its a bit different and bit bigger, and then the if you click it the flashing will appear.Regards, Gerrit

All I have to do is move my mouse over a 2D panel and let the tool-tip appear. After it appears, about a half-second later i'll get the flashing. So the tool-tip is only visible for about a half-second before the flashing occurs.I'm not sure what you say about it loading the proper font for the tool-tip - a half-second is too fast for me to really notice what kind of font is being used.

Hi Joshua,maybe it happened only when moving over a gauge, i can't recall exactly because it hasn't happened for a long time. Since i changed from the default planes to add-on ones i think. But for me i'm sure, it was related to the font of the tooltip. So maybe it helps to change something in font setting, like from standard to cleartype or vice-versa.edit:A while ago i also changed my habits from starting the sim in fullscreen to starting it in windowed mode and then switch to full screen. That might be another solution. Just for what it's worth :)Regards, Gerrit

Try installing an older video card driver, like I did...and see if that solves it.RhettAMD 3700+ (@2585 mhz), eVGA 7800GT 256 (Guru3D 93.71), ASUS A8N-E, PC Power 510 SLI, 2gb Corsair XMS 3-3-3-8 (1T), WD 150 gig 10000rpm Raptor, WD 250gig 7200rpm SATA2, Seagate 120gb 5400 rpm external HD, CoolerMaster Praetorian
