screensize dos games

I have a desktop and a laptop, both pc's have Windows XP, Sp3. On both pc I have the same games (Windows and Dos). Since a few months the dosgames on my laptop are no longer full screen but with high resolution, that means small screen. My Mahjongg and patience games are to small. I search everywhere to find a solution to get the games with a full screen again. No results. The changes you can make in a PIF files has no effect on the games. Why is that only happens on my laptop. On my desktop the dos games are all shown at full screensize. I have enough memory, enough free discspace. My laptop is three years old. The games are located on a external disc (size 156 Gb, free discspace is 140 Gb). My laptop is in a good condition. Everything works as it should.

Ho has the answer on my problem. Don't look at the languages mestakes. I'm Dutch.

Try pressing "Alt" and "Enter" at the same time while playing the games.
This should put them in full screen mode.

with the combination Alt Enter I go to my bureaublad (i dont know the englisch word for it). I also tryed other combinations such as Alt Esc, Alt Spacebar, Ctr. Esc etc. Nothing happend.

bureaublad=office booklet?

I don't know if that's correct, I used an online translator.

I mean my desktop.

Well, that was a quality translator service.
