switching forms

I have made two user forms. Both I have up on the screen.
What commands do I use to switch between the two
while leaving them both up.

Seems like the program freezes as soon as I open the second form

I am using Excel 2003.
Thank You

Forms display

Hi,

Did you try showing the userform in modeless mode ?

userform1.show vbmodeless
userform2.show vbmodeless
