Can anyone tell me how the mouse deals with overscan? I am having some problems with my tablet driver and overscan. Basically, I cannot get the mouse pointer to the edges of the screen. Should I scale the numbers so that they are outside the system window parameters of 640 x 400? I read in the ROM kernal manuals that GFXBase Library contains these numbers and references these whenever doing mouse operations. It seems that the system clips the mouse to the window. A question, in overscan, is the left side of the screen's x coordinate less than zero? When the mouse is at " zero " in x, it is not fully to the left side of the screen. I am using IECLASS_POINTERPOS to position the pointer with the tablet. I guess I need to know how overscan works. Is there any documentation? neil -- Only 3179 shopping days left till the next millenium! Neil F. Richmond INTERNET: celia!neil@usc.edu Rhythm & Hues Inc. UUCP: ...{ames,hplabs}!lll-tis!celia!neil)
