I have a collection of worksheets. On each worksheet there are a number of textboxes, each connected to a ther own cell.

They all have a fontsize 12 and are used to keep comments that relate to the calculations on the other part of the worksheet.

When I select a textbox to enter tekst the fontsize changes to very small and I connot read what I am typing.

After deselection of the textbox the fontsize changes back to its original fontsize 12.

The problem occures in every version of Excel. Origanaly they were made in Excel 2010 and now manetaned in Excel 2013. The workbooks are saved on a SharePoint site but a workbook saved on a harddisk of a computer shows the same problem.
