Excel Macro workbook_open() BUG with addins?

[lang0477]

Hello guys, I really need your assistance
I wrote a VBA macro do some calculations and I added a splash scree
with:

Private Sub workbook_open()
UserForm2.Show
End Sub

now here is the problem, I save my macro as an addin, and enable thi
add-ins in excel "tool". now if I open an empty(new) excel workbook
everything includes my addin work just fine, my userform2 displays a
the begining.
but if I open any existing(saved) workbook that contains data, it wil
behave like this:
userform2 displays as before, then it disappear as expected(After fe
second), but there isnt any workbook got opened, the excel window i
here and it is gray, i can mannually create a new workbook or clic
open file button to open other workbook, but it doesnot open th
workbook I chose automaticlly after i double click on the workboo
icon.

I am pretty sure the problem has something to do with workbook_ope
sub,
if only I erase this sub, everything will be just fine.

I have searched so many online tutorials but none of them addressed th
problem,
anyone knows what might be the reason?
thanks a lo

Look in Tools=>Options and see if Ignore Other Applications is checked. If
so, uncheck it.

Good for you.

I just looked, the "ignore other application" was origionally unchecked

the other alternative for this type of problem is usually to close excel,
then go to the Run menu under the Windows Start menu

enter

Excel.exe /regserver

and click OK.
