Difficulties in copy , cut , paste files

When using copy / paste for files- I get annoying window saying " A required DLL file could not be loaded! (Channel DLL)
Errorcode: 20 "

After 3 times the operation is carry out
BTW in right click on the mouse (marking a file ) I get the message only one time before it operate

 

While doing a quick google for your problem missing file error, I found 3 references to this file. There may be more but look these over and see if any apply:

1]You have a microsift wheel mouse? Cause there is a DLL with that name when you install intellipoint. To resolve the problem just re-instal mouse
drivers. You can go here to download the intellipoint software wich include the missing DLL or install the software came with your mouse.
(This is a copy N paste from the post I found. I don't use this mouse so I can not verify if it is correct but a copyNpaste would involve your mouse).

2]Quicken program: Do you use "Quicken "? Missing Channel.dll error was most often found and connected to a Quicken problem. Channel.dll is a quicken file.

3]One trojan virus:
one virus etrust

==========
My guess would be that the mouse driver update looks to be the most promising.

Do you have a "channel.dll" on your harddrive when you do a file find?
