DotNet Fx1.1 Sp1 Issue :- Need Urgent help !!

[krishnan]

Hi all

I have a custom usercontrol in my window form "frmsett.cs" .
"initializecomponents" of "frmsett.cs" initialises usercontrol

This usercontrol is derived from a base component class.
Usercontrol populates printer informations.

we populate default printer related informations to usercontrol through
Pinfo() method (a function in base component class )
Pinfo() invokes getinfo()(another function in base component class ) using
methodinvoker and asynccallback

My "basecomponent" class definition starts with
[ClassInterface(ClassInterfaceType.None), ComVisible(false)]

when i call frmsett.showdialog() Applcation is developed and works perfectly
in .NET framework 1.1

Then I installed .NET framework 1.1 SP1

Here the problem begins. When application executes ShowDialog(Only at first
call) It hangs for some minutes (5-15 mins) before showing the dialog
"frmsett" . If we clicked second time it will display the screen
immedialtely.

Anyone come across this type of issues???
Is there any problems asynccallback with methodinvoker in .NET fx1.1 SP1
What is the reason for this problem in .NET fx1.1 SP1???

Thanks a lot for any tips !!!!
