Word suddenly switching my font from 11 pt to 8 pt

[KHazelitt]

I recently got a new computer at work and I've found that when I'm typing along it will switch my font size from 11pt to 8pt. The scenario is usually when I've finished a memo and use a macro for whom to cc:, then save it and use a macro to put in a footer so I know in which folder it can be found and then print with Ctrl P. I don't know if I'm hitting some quick key that makes it do this or what.



I know the quick key for decreasing font size 1 pt is Ctrl [ and that's right next to Ctrl P (for when I print), but this decreases it 3 pts!

I'm very frustrated and can't find anything online!

Thanks!
