I'm having the same problem with my Tview. Sporadic but consistent (if that makes any sense)
Overnight or while I'm at work during the day, my PC seems to "forget" about the TS drivers.
When I leave for work in the morning or for home at night, I have to wait about 7-10 minutes before the drivers "catch up." I can see that touchmon is not loading in the system tray. I've tried putting it in the startup (msconfig) with nothing else checked. Still the same problem...
If I touch the screen, the mouse looks like it comes up from the lower left corner (like stretching a rubber band) , and then when I release, it snaps back. It must be clicking because 2 secs later I'll get the right-click menu for the taskbar.
I still have the keyboard in the car, just because of this and I'll have to esc everytime the shortcut menu comes up.
It doesn't matter if I reboot a million times. It won't recognize the drivers, until it feels like it. Same as you with trying calibration (esc on the KB or right-click on a mouse will get you out of that whitescreen).
Once its ready, I have no problems, I can reboot, cold start, etc. until its left for a long period of time (overnight, @work)
I've tried all of the drivers I can find, with no luck still.
Glad (but not really) that someone else is having this problem.
I'm wondering if there is a program that you can control what drivers/services load first??
Oh yeah, XP SP1, Dell Dimension 8100 p4 1.3 128rdram (also wondering if it might be lack of ram)
