Multiple windows when clicking Mailto:

Two PC’s (at least) having the same problem: when you click on a Mailto: link on a web page, multiple windows (20-30?) open until all memory has been filled (I’m guessing). The PC’s: one is W2K SP2 w/ Office XP SP2 (& VBA & Macro patches). The other is WXP SP1a w/ Office XP no SP or patches.

Any ideas? Thanks.
