When using the #TV.Guide.thumb tag the image does not work. For example in Metal it is used to show the thumbnail of the channel in the infoarea. There is no image displayed.

When printing the #TV.Guide.thumb tag with a label control it shows the correct value "thumbs\tv\logos\Nederland 1.png". When hardcoding this value in the <texture> tags the image shows up correctly.

Probably the image control does not notice that the value of the texture tag has changed.

Seen in Metal and Crystal

To reproduce:
* Start MP
* Go to TV Guide
* Select a program on a channel that has a thumb
* No thumb is displayed in the location where the image is supposed to be (left side of the info area)
