[AccessD] A2K: <Application Title> can't run the macro or calback function '<FunctionName>'

Hi All,

Here is a tough problem I can't find explanation of:

I'm getting (sometimes) the following error message:

A2K: <Application Title> can't run the macro or calback function
'<FunctionName>
Make sure the macro or function exists and takes the correct parameters.

<FunctionName> DOES exist but it's located in library database and it's
called from TOOLBAR button - i.e. its name is in the OnAction property of
toolbar button.

I wrote above that I'm getting this error message SOMETIMES because it
appears for some FE program databases and doesn't appear for others but if
it appears once for an FE program database it persists to appear.
I know workaround - creating wrapper module in FE database but this isn't
always desirable.

I've got this problem first quite a while ago - somewhere in 1998(?)  and it
was in Access97 when I installed some new software from MS (Office97
R1?)  - I can't remember which - before that I used calls from toolbar to
library databases' functions without any problems...

Have anybody seen any explanations/descriptions of why this problem appears
and how to fix it without wrapper modules?

TIA for any info,
Shamil
