Older Pending issues & bugs
(not seen since a while…) VIEW CCT on data cubes may (rarely) cause occasional crashes. The origin of the bug is most likely related to the pencil colour handling in the graphic library, but yet unidentified. Work around: try again, it may work !
(confirmed 04-Jan-2023) CLEAN may stop with Zero iteration if it already did so because of improper input parameters before, even after resetting the parameters. Probably a missing initialization of some Logical variable. Unfortunately, the only Work-around so far is to restart imager.
