TAdvOfficeTabSet

VCL TMS VCL UI Pack
1

Hi,


We have an odd problem with a client using our application - it is on any forms that contain a TAdvOfficeTabSet - it comes up with 'Error reading otsDateSelector.AdvOfficeTabs: Invalid floating point operation' when the form is created.  

The application is running from a server and only happens on some PCs and not others - the app is built in Delphi 2007 and using the latest TMS components

Any ideas?

Thanks

Sorry, without further information or details, it is extremely hard to guess what is going wrong.

Is there something common about the PCs where this problem is occuring?

No anything immediately obvious .. as they are Windows 7 x64 Service Pack 1 build 7601 and display mode: 1920x1080, 32bit ... which is the same as my PC .  I created a simple test app that was just a single form. had a TadvOfficeTabSet & Eurekalog and this failed for them also.  I don't know if the following helps ... seems to be failing on ..    Result := Rect(round(sizerect.X), Round(sizerect.Y), Round(sizerect.X + sizerect.Width), Round(sizerect.Y + sizerect.Height)); // line 2512 in AdvOfficeTabSet (DrawVista)

It's unclear what is happening.
Would you be able to log the values of the parameters of the Rect() call to see if there is anything unusual with these?
