Trouble with COMCTL32.OCA

I have several apps which are launched from a common shell program. The app is VB4 running on NT 3.51. I use a toolbar
to switch between the shell and the other apps. I am getting
Error 48 error loading DLL when I use the toolbar to switch apps. If I use ALT-TAB eveything is OK, that is, the other
app is running and able to function properly.
If I add COMCTL32.OCA the problem goes away. Why ? I thought
OCA files were created on the fly by their OCX.

stormbridge,
For every control (or multi-control) you add to your project, there must be a reference library (OCA or DLL) that will be automatically added to the Project - References list. That's why your program works just fine when you add the OCA file. It seems that your VB can not either locate the OCA file automatically or it can not add it to the references for some other reason, probably because it is incompatible with your OCX version.
