Question : alt-tab/mimimize/restore sometimes flakey

I tend to work with about 10 apps open in XP Pro SP 3, so I use alt-tab regularly to move from the current app to something else in the stack.  Usually it works fine, but intermittently I tab to another app and not much happens.  Alt-tab disappears, and the task bar shows my chosen app highlighted as the (new) current app.  But the old app still displays on top (with an inactive title bar).  If I right-click on the icon in the task bar and select "minimize", there's a trace of it minimizing over to the task bar.  Then when I click "restore", then it's on top and active.

Any suggestions?
