Does anyone has a problem with entering numbers and solved it?

Yes...different solutions though

1) totally blank page when you go into a section?
or
2)  a "$0" showing for an interview field that won't let you change it?  (not a simple "$" showing.)

or something else....I may not have a fix for other stuff.

I have a $0 showing but for some medical forms it will not me enter a number and it will not show my mouse pointer in the entry box. The mouse is working otherwise.

Here you go....
