problem with IE

am having a strange problem which started last night on my scrabble game which is played on the internet through e-mails back and forth from the game to each of the two players. Suddenly my game screen comes up small and the board is incomplete. If I click restore then I get the full board and proper page size. This gets to be pretty irritating though as I use some of the game features as then suggested possible words comes up small/incomplete and dictionary definitions does the same. I did notice an error message last night but assumed it would correct itself this morning when I turned the computer back on. When I click on the Internet Explorer Browser the home page is coming up the same way. By incomplete I mean the page will not display the right side as the page is too small and also there is no slider to move the page horizontally.

My e-mail page comes up normally--the regular size, not maximized. I want to get the regular size internet page displayed each time. Did I "slip a cog" and do you know where I go to reset this?
Thank you in advance
