URGENT!! Input font size changes in spreadsheet activex textbox

I am leaving my job in a few days and the project I have been working on for the last few months ends up breaking only on one of the computers. The font within my activex text boxes keeps changing. Most of the time it shrinks to a non-visible size. Other times it grows. Is there a macro I can write to prevent this or even fix it when it happens? I have already found a way to stop it from changing the size of the text boxes but I can't find a way to prevent the font size from changing.
It seems like it is triggered when the laptop is redocked or undocked. I hope this helps. Also. I am using Excel 2013

It looks like this may be the code you are looking for but I can't quite translate it:

From what I could tell the German word Aufgaben can translate to several english words: tasks, chores, jobs, missions, assignments.

It's a start.
