Transition for 5.1.2.3

Working with OpenDCL 5.1.2.3 in Windows XP found some problems in project done in the version 4.1.2.2. 

1 - the form of the included image doesn't show the icon to close. 
2 - other form disappears like this of the work area and it is necessary to close OpenDCL and to open again. 
 
This only happens with Wuindos XP or me I should reconstruct my project.

Thanks

Can you email the original file to me?

Thank you Owen, 
I am preparing the files to send for you. 
You will receive the versions 4.1.2.2 SP2 and 5.1.2.3. 
For commercial problems I will send for your personal e-mail OK?

Hi Owen, 
I sent the files for you. 
The images below show the main form of my project working in AutoCAD 2006 to 2009.

Thanks
