A good basic "Paint" program?...

Hey guys -

I'm looking for a good, small graphics editor (Paint) program - needless to say, one that runs portably - and I was hoping you could help me find one.

I'm not looking for a high-powered app like portable GIMP, just something that does what MS Paint does, w/ maybe a few more features, particularly the capability of zooming OUT a ways (not just IN), which Paint doesn't do.

I have Irfan View, which I do some work with, but cutting and pasting with Irfan is problematic. Whenever I attempt to past into Irfan, it converts itself to a window containing the copied/cut segment (basically, a clipboard view), and the original window disappears.

Yesterday I found an open-source proggy called "MrImage" (which is less than 5 M unpacked) and does what I want it to do, except for one tiny problem: It acts kinda flaky. Sometimes it closes down for no reason, other times it REFUSES to close down when I tell it to, etc. Apparently the development on it has ceased as of sometime in '04, but it appears to be open-source, so perhaps someone esle has improved it? (Or so I hope).

Any ideas, guys?...

Thx
