Hi Chantal,  I have had the same issue.  It happens when I am typing in entries too quickly.  I must hit the TAB key and it messes up everything.  Close out the page you are on and restart your entry and you should be fine.

Hi Chantal,  I have had the same issue.  It happens when I am typing in entries too quickly.  I must hit the TAB key and it messes up everything.  Close out the page you are on and restart your entry and you should be fine.

This is not from hitting the tab button. This happens if I use the shift key to type a capital letter ... then it  locks out the numbers and closing the page is not an option as I have already typed 1/2 a page of description in the invoice.. I would loose that. What I have to do is shrink sage then open a word document  and just type random numbers. Then pull up from the shrinking and when sage is back you can continue on.... it is extremely frustrating... This happens on at least  4 of my clients on their computors as well. 

Copy and paste what you wrote into word and repaste it later when you reopen the invoice.  It is just a suggestion.  That's what I do.  Good luck.
