As I am having bugs in a graphic program module (who doesn't, uh?), I'm trying to debug it. So when run until cursor it changes to the user graphic screen. No problem so far, but as I try to go on tracing I have to keystroke alt+F5 (to changeback to the ide), but it shows a user text mode screen (the MSDOS one). Pressing alt+F5 again returns to the RHIDE window and can go on tracing, but when alt+F5 is pressed again it will NO longer show the graphic mode user screen, but the text mode user screen instead. (How is it supossed to debug a graphic module whitohut seeing what it does?!! Maybe it's a useful exercise to improve abstract thinking, uh?) Anyway, if you know why it happens, or know how to solve it, please do tell me about. 2) The thing is that if I try *ANY* SVGA graphic mode under a WINDOWS 95's MSDOS window (even in whole screen mode) the system gets hanged up (you know, a only-cold-reboot-solution crash). It all happens just as I initgraph() with a SVGA mode (just like a *simple* 640x480x256colors). I know the .exe is ok because it DOES work in PLAIN MSDOS. Is this *normal*? I mean, is grx expected to be used only on plain MSDOS or is there something wrong in my system configuration? Thanx in advance for reading this ugly-mess-idea text! ==> Diego Dominguez <== diegodc AT arrakis DOT es
