Thanks for the link but my problem is with EXE files (amongst others) so, as stated in the MS article, you can't use that method to change the behaviour.
By comparing to another machine, I have found is a set of keys in the HKCU registry that shouldn't be there -
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe]
"Application"="AcroRD32.exe"
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe\OpenWi thList]
"a"="AcroRd32.exe"
"MRUList"="a"
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.exe\OpenWi thProgids]
"exefile"=hex(0):
Having now removed them using REGEDIT (& I remembered to back up my registry first!) I have now re-installed Acrobat Reader without experiencing problems (haven't rebooted yet, but I'm pretty sure it's fixed) - e.g. I can still use REGEDIT, launch IE7 or Firefox from icons that didn't work before.
I have no idea how those keys got there, but they're gone now ;-}
