This was an old problem that seemed to fix itself a while ago, but since the server downtime recently it's back. I use a blunt-force trauma character sheet that I created some years back for Battletech and a big part of the sheet is tracking damage with several number sections. For context this is an example of the code for one of the fields. Just in case I've done it wrong, again I made this years ago and remember NOTHING about how it works. I removed the <> brackets. input type="Number" value="0" name="attr_LAAM"/ So on the sheet I can input a number by highlight and type, this works fine. However it I change a value with the little up/down arrows in the box any changes made by those arrows are lost. This only happens when using Firefox, I downloaded Chrome to test there and it works fine, I did check that my Firefox is up to date. My Firefox has no Add-ons and I did try clearing the cache. Were I to take a wild guess at the problem, I noticed on Firefox using the arrows doesn't seem to make the field active, with the little blue highlight, while it DOES on Chrome. However using the arrows then making other changes or manually making the number field active then changing focus doesn't seem to help. Without question this is a minor inconvenience I know, but this game involves a lot of small number changes, being able to use the arrows speeds things along considerably. We will use Chrome of course for now, just since this started right after the server downtime I thought I'd bring it up in case it's indicative of a bigger problem.
