Man you guys are 4 for 4. Some really good tips. Huub, I currently do as you by saving my current project as the default flight.
And Tom, your desktop shortcut trick fits the immediate need as it saves a few more mouse clicks. And since I don't have FSX loaded - no conflicts there.
Quax, working on the translation for your suggestion, looks like it might come in handy at times when already booted into FS9 and need to make a quick change like turning a layer on or off.
Stefan, been considering FSRepaint also for just the reasons you mentioned. I'm probably a little over the top when it comes to aligning panel lines and shading and other effects across texture files. And when you're adjusting a curved panel line stretched in one oblique direction across two textures and the textures are not in the same scale, you can wear the paint off a key board letter booting in and out of the sim so much!
So, looks like there's room in my expanding tool box for all of these suggestions because they each serve a little different need from the other.
Thanks so much for sharing your experience,
Steve
