Something strange has happened to my Outlook Express program - after a few YEARS of normal operation it now has a strange way of showing messages and I can't return it to default.

When I click on a message to view its contents, the new wondow showing the contents is only small (about 1/4 the size of a normal one) and can't really be read sensibly, so the first thing I ALWAYS have to do is maximise it to read.

I suspect someone has accidentally pressed some secret key combination (CTRL/SHIFT/something) that has changed its default setup, and it's REALLY IRRITATING.

I'm using Outlook Express 6.00 on a Windows XP Home system. Any suggestions for a solution would be appreciated.
Try this.
Hover your mouse over new message window border/corner, until it changes to double arrow. Click, hold, and DRAG borders to the size, you like.
Hold CTRL key, and close that window. Reopen. Is it in right size now?
Ultimately, right click on OE icon, go Properties>Shortcut tab
At Shortcut key choose "Maximized" from drop-down menu.Thank you VERY much. That worked fine and things are back to normal!!
You're welcome
Which way did you go?
