Hi all,

Using a graphic application in a dos box under Win95 gives me some
problems, depending on the hardware (I use GRX20). On a 1MB video ram
system, the box automatically switches to full screen when initializing
to graphics mode. On a 2MB video ram system, a white screen appears with
a message saying something like "Please switch to full screen...".
When I do it, the dos box aborts with: This application can't be
restored + OK button.

Is there a programmatic solution to automatically set the dos box to
full screen inside my application ?


Another graphic related question: it is sometimes impossible to save
a full screen graphics to the clipboard. When I set 16*640*480 mode,
I can ; when I set 256*640*480, I can't (I get the message
Impossible to copy the screen contents to the clipboard) ; when I set
the 256*800*600 mode, I can't neither (sometimes Exception 0E from
VDD.VXD).  So, what is the size limit of the clipboard and can I
change it ?

Thanks for your help.
