	I'm back...he,he		};-)

	There are 2 nasty problems that bother me, and I will thank help in
ANY of these:


1)	First of all, I must tell you that I am programing (if almost
ramdom keypading around can be called "to program") in C whith RHIDE
v1.4. 
	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!
