Greyfox, I was only saying that a number of senior members were AWARE of the problem - not that they were experiencing it.
However at least five other members have described experiencing the 3 second delay in Windows Explorer and several have confirmed that SDHelper switches the delay on and off.
Most installations do not show any evidence of an SDHelper bug and there must be some special factors that trigger the problems.
I myself have not experienced any IE7 related slowdown problems.
I have experienced the Windows Explorer 3 second delay with the following configurations:
XP Pro with XP2 and XP3 - Using both IE6 and IE7.
I run a very lean setup with only 22 processes showing in the XP Taskmanager.
The only memory resident applications I run are AVG Free v8.0 and TeaTimer.
AVG Free is installed without Linkscanner (and Toolbar) or Office Plugin.
I use the XP Firewall and have SpywareBlaster v4.1 installed.
Applications installed with IE addons:
Java JRE 1.5.0_15
Acrobat Reader v5.0.5
Adobe Flash v9
Apple Quicktime QTPlugin v7.1.3
I do not run any addon IE toolbars
Applications with Windows Explorer integration:
Treesize v1.72
Agent Ransack Search v1.73
Winzip v6.3
I have found the following members posting reports about the Windows Explorer delay in different threads:
