[AccessD] A2K: Code Failures on Win 98 Machine

Hello all
I have 2 issues still outstanding with my latest app. On win XP or Win 2000 boxes the 
following code snips work fine. All machines are WIN 98 and WIN2000 and 
WIN XP boxes (No Win 95 or Win ME) all running Office 2000
In fact the Office 2000 install is off the same MS Office 2000 install disk - <sigh>
But the code snips fails only on the Win 98 machines

Anyway here is the snip that fails in WIN 98 - but is cool in WIN2000 and WINXP
strSkinsPath = Left(CurrentDb.Name, Len(CurrentDb.Name) - Len(Dir(CurrentDb.Name)) - 1) & "\Skins\" & strSelectedSkin & "\"

But of course the "hard coded" following snip below in place of the one above does work on all OS's
strSkinsPath = "C:\Program Files\TruMan\Skins\" & strSelectedSkin & "\"

Also I am getting failures with the bookmark property in the Win 98 boxes.
Same Access/Office version just different OS

Basically I have a combo box on a student form to use for a search tool.
You pick a student name from the combo on  the footer of the Student Form
Then using .findfirst and .bookmark I can (normally) go to the record. 
But it fails on the Win98 boxes and throws me out of the app and on occasion needs a re-boot.
So to that end - does anyone have any .findfirst and .bookmark code that works with a WIN 98 box?
Even code to determine .AbsolutePosition would be fine. I can then use docmd.gotorecord stuff
Many thanks in advance
