[Insight-users] GLSliceView

[salah]

Hello,

I used a slice viewer which is actually an extention of the GlSliceView class (from
which it inherits its main functionality). Newly, I get a strange behavior with this 
viewer. 

Normally, the viewer displays the image details at the lower-left corner as well as the 
location and value of the clicked voxel location (lower-right). These details do NOT 
appear SOMETIMES. The viewer behaves otherwise ordinarily. When this problem 
occurs, then all instances of the viewer in my application will behave similarly (i.e, either
all display the details or all do not).

Could anybody guess what the problem is?

Many thanks,
Zein
