Toolbar not appearing

Hi,

I am having a problem with a toolbar not appearing on some PC's that are trying to access it.

I have tried to show the toolbar by doing the following:

1. It doesn't appear in the list of toolbars under the 'Customise / Toolbars' menu.

2. Clicking on the 'Customise...' option within the 'Customise / Toolbars' option, in the window that opens with the toolbars it is not listed.

3. Clicking 'Add from file' in the window described in 2. above and navigating to the required .tlb file and adding it this way. The toolbar still does not appear.

This problem only seems to occur on certain PC's, on others it is fine.

Could anyone please help to let me know why this happens and if there is anything I could do to resolve it?

Thanks
Simon
