Graphics pages get corrupted after conversion to 5.xx format  

When upgrading a project to 5.xx format, sometimes the graphics pages get corrupted.

This usually occurs for projects that have been upgraded in several stages from 3.xx or 4.xx to 5.xx.

The corruption occurs if the project is stored in 5.xx format but there is no Global.ctl file in the project directory. To check if the project is stored in 5.xx format, read the value of the third byte in any .ctg file. It should be "6".

If the project is stored in 5.xx format but has no Global.ctl file, then find or create one and put it in the project directory. Any Global.ctl file whose first 4 bytes match the first 4 bytes in the .ctg files is acceptable. A Global.ctl file can be created by creating a new project in Citect Explorer.

To be safe, force an upgrade with [CTEDIT]Upgrade=1
