Excel 2007 :: Form Command Button Label Length

We just upgraded to Excel 2007 from Excel 2000 and have run into a challenge relating to labeling a form command button. It appears that the length of text for a command button label has been shortened to 31 characters when setting the name using VBA. No such limitation shows up when I manually create such a button.

Following is the code that used to work to create the button and label in VBA (Excel 2000):

VB:
ActiveSheet.Buttons.Add(2.25, 13.5, 443.25, 17.25).Select
Selection.OnAction = "PatientSelectedButton"
Selection.Name = "CheckFormButton"

[Code] .....

If I change the string I want to use for the label to 32 characters, or less, this code works (Excel 2007).

VB:
ActiveSheet.Buttons.Add(2.25, 13.5, 443.25, 17.25).Select
Selection.OnAction = "PatientSelectedButton"
Selection.Name = "CheckFormButton"

[Code] ....

I have to admit that this is the last item that I thought would break!
