Command key issue with Microsoft keyboards

I've been using a MS ergonimic keyboard for several years and it apparently died.

I bought a MS Comfort Curve Keyboard 2000, it typed fine, but you couldn't program the special keys so you might have an Application pop up when you hit F2 or Andother App if you programmed in F3. or the key for Mail launch the Mail problem.

MS said bring it back because it's been upgraded and the new model 3000 was better.

Well, I've gone into system prefs clicked off the proper boxesl, LIke Swap Apple's Alt key for the Command key.

In a nutshell The Alt Key doesn't work to cut and paste, etc.

I can hit the next key over the MS key, as the command key, but that's not the way dit sholld work.

Their engineers haven't come up with a solution becasue it's hard to find a Mac n a MS world at their tech support.

I haven't called Apple Care, because they'lll lay it off to a third party problem, namely it's MS procuct.

I've had Macs for years and this is the oddest, quicky things I've seen.

Anyone else out there experience this or better, can suggest a fix?

I just can't get used to the Flat Keyboard that Apple had.

This MS keyboard is ergonomic a comfortable to use.

Thanks
