[Insight-users] Problem building QtImageViewer

[Jarek Sacha]

Image display works great and pointer is very responsive now. 
A small suggestions for improvement: number displays are currently
truncated to 3 digits only so you cannot see correctly larger values for
intensity or cursor position.

Thanks for the fixes,

Jarek
