text: help with excel - weird squares - help!? i'm pretty decent with excel, but all of a sudden, i have weird squares in place of where the decimal points used to be.  anybody have this before?  what can i do?   the rest of the numbers in the cell are unaffected.  this happened to all of my excel documents.  is this a virus with my font?  it looks like:  67@889 812@45 3@90   @ = square it would be interesting to know if the square behaves like a decimal point - that would mean the following would be likely to solve the problem... this is for w2k,  xp may be slightly different..  start - settings - control panel - regional options - numbers the entry against "decimal symbol" should be a . but i suspect you'll find a square here.  change it to a dot, then click apply.  if it's not a square, change it to something else, then back to a dot, then click apply.  hope this works.  i was just able to replicate your symptoms on my pc this way, so i'm feeling lucky.
