Something very strange began happening today. I started FSX and then I clicked on "computer" on my desktop to check something and the address bar was flashing and I couldn't open any folders. I then discovered if I hit escape in FSX or choose End Flight from the Flights menu the flashing stops. If I click on Continue Flying the flashing starts again. Pausing the flight didn't stop the flashing. I noticed also that if I mouse over a program in the task bar that is running it flashes also. The last thing I did before this started was to install Megascenery4x Texas North and South and Colorado V3. Disabling those sceneries didn't stop the flashing. It occurs with no programs running except FSX. I tried restarting my computer but that didn't help either. Has anyone else ever had this happen?
