I start up Citect and I can see that in the Graphics Builder, Project Editor and Citect Explorer appear in the Taskbar, however my Citect Explorer is no where on the screen to be seen. What is going on and what is causing this problem. 

This is caused by a corruption to the CITECT.INI file. The way to rectify this problem is simply to edit the CITECT.INI file in the following sense.

The code in CITECT.INI that were looking at is:


The definitions/values for it are as follows (values are in pixels and based on screen res of 640-480)



A   Start Up Status (During application start). DO NOT USE 0 or any other number than the ones shown

Allowable Values

0=Do not Start Citect Explorer (Closed)


4=Restored (Normal State)


B   Distance from left hand side of the screen (Depending on Screen Size 0-640)

C   Distance From top of Screen (Depending on Screen Size 0-480)

D   WIDTH OF WINDOW (Depending on Window Size up to 640)

E   HEIGHT OF WINDOW (Depending on Screen Size up to 480)

Note: With the very first value 'A', I would recommend either leaving it as 4 or 3, or DO NOT touch it at all. It caused an application error every time without fail when the figures change and I had to restart the computer to get Citect running again.

Also the values for B, C, D and E are all in PIXELS, so the centre of a screen with a resolution of 800x600 pixels would be 400x300.

Note: To find your screen resolution, simply right click on an empty space on your desktop and then select "Properties". Go to the Settings tab and check the Screen Area



This would start up CTEXPLORER at the top left hand corner of the screen with a size of 800 pixels wide and 600 pixels high.
