[Brains-users] ROI tracing

[Laura Acion]

Hi Roberto and the rest,

I have experienced this before and I showed the problem to Hans or Ron I 
think. I am not sure how this has evolved since I did show it to them. I 
had also troubles with the venous blood traces.

Also, now that you mention it, I was at the point of submitting a bug 
today because in the last release for red hat 4, I am having this kind 
of thing happenning during the edition of the cran mask traces. As I 
edit in the usual way, funny shapes appear that sometimes disappear 
after closing the roi but some other times stay in the edition and need 
to be specially edited. It is difficult to describe, but if an example 
is needed I will be happy to generate some.

Thanks!
Best wishes,
Laura
