Combobox size and list within keep shrinking

Hi guys
I'm not experienced in writing vba code. I have created an activex combobox to enable me to quickly move to another worksheet in my workbook. I have managed this mostly by following youtube videos lol!
It works perfectly (surprisingly) BUT every time I click into the box the text within it shrinks and also the size of the box changes when I come back to the worksheet with it on.
I am working in Excel 2010 on windows10 64bit.
I have attached the file accordingly and the combobox in question says 'Go To Batch'
I have googled the problem and searched on here to no avail so far and just wondered if someone could help me.
Many thanks in advance
Andy

A well known Excel bug, ActiveX controls are unstable on worksheets, has been there forever.
Possible workaround would be to recreate the combobox everytime it is used.

While this does not answer your direct question, given what you want your code to do, I thought you might find this "Neat Go To Sheet Selector" that I posted a while ago in my mini-blog to be of some interest. You can find the code, a full description of its use and a demo file at the following link...

A Neat "Go To Sheet" Selector

One thing I did not mention in that blog article is that you can install all of the code to a workbook with blank sheets and then save it as a Template file. Then, when you are going to have a project with a lot of worksheets, you can open the Template file instead of a normal blank file and all the code will automatically be in place.
