SQL Server Tablet PC Incompatibilities

Hi everyone.

First off, please allow me to extend my thanks to those of you who've helped me with the one or two questions I've had over the last month with regards to SQL Server Express. We more or less successfully rolled out a new version of our software migrated to SQL Server Express to our client today and they were very happy with it.

There is one perplexing problem though. There were about 20-odd installations on Sony VAIO's which all went relatively seamlessly. One of the users, however, has a couple of Panasonic ToughBook CF-19s with Windows XP Tablet PC 2005 Edition with SP2 installed. His are the *only* machines which our solution is not working on.

By way of description, the system is a revamp of a Microsoft Access legacy platform and in order to simplify the conversion, I opted to use ODBCDirect as well as Jet in different parts of the program; not ideal but I had no choice really. So the program accesses the server in two ways. It either uses an ODBC DSN created using the relevant settings through Control Panel or it uses an ODBC-linked Access file linked to the server. These connections both work fine on all the Sony VAIO's and the program is able to start.

On the ToughBooks (we've tried it on two with the same result), I'm sure that the ODBC connection is working fine, as the "Test Data Source" button executes favourably and says that the test succeeded. This is further confirmed during startup of our app which automatically attempts to login to the server and displays the success of that.

My suspicion, therefore, is that it is failing when it attempts to open the ODBC-linked database (I can't be 100% sure since the client is not going to be happy about me installing debuggers on their pretty machine), but all evidence suggests this is the case. Does anyone have an idea if there is something in Tablet PC Edition which could be causing this failure, since it has all worked fine on XP Professional installations on different laptops and desktops.
