Open webpage in new IE

I need this feature and read this post Open link in new browser window

but then it didnt work like I expected it did call the mozilla but and then it was closed I dont know why.

I dont need to open the page in mozilla IE is fine for me. and then I figure out a way to work around and I want to share it in case someone need it.

here we go

ExecShell "" "iexplore.exe" "C:\whatever\a.htm"

ExecShell "" "iexplore.exe" "C:\whatever\b.htm"
