Excel opens differently alternate times

This is a wierd one. If I start Excel 2007 by double-clicking on the file name, it opens differently at alternate times. One time it opens OK, showing the Personal macro if I do a View>Un-hide, and it shows the Google toolbar. The next time I open the same file, Excel does not give me access to un-hide the Personal macro nor does it show the Google toolbar. This happens on a fairly consistent alternate basis,one time allowing access to this information, the next time not, the next time allowing it, etc. I told you it was wierd. Has anyone ever seen this happen, or even better, has a solution?
