Reference image not visible

Hello,

I'm finding it impossible to work with images on one of my computers. I often use maps or other images as a background for my drawings. When I add an image, or an OLE object from a pdf, it is displayed as one big pixel - i can not see the image while drawing. It only appears when i change its properties, for example line color or any other property. However, after scrolling with my mouse the image disappears again.

This happens only in model space - i am able to print the image, but it isn't visible while drawing. It is making my job impossible to do.

I have tried updating my graphics driver, reinstalling draftsight, installing an older version of the program. Nothing solves the problem. I have worked with draftsight on several machines and never experience such issues. Please help.
