Cool VL Viewer forum

If I try to save a snaphot with Cool VL Viewer 1.26.4.23 as soon as the the window to select the filename and the directory of destination appears, the viewer crashes:

As shows the backtrace, the crash occurs within your system GTK library (in g_free()), not in the Cool VL Viewer code itself... I can't either reproduce this bug here.

You are right.
I recompiled glib2 from glib-2.33.6.tar.xz sources package and now Cool VL Viewer-1.26.4.23 works for saving snapshots and upload images.
Thanks.
