well i may just indicate a couple of tricks that sometimes help
1) the first is obviously in case of apparent freezing do nothing...let a
chance to gimp to process all data even if that may take (i.e if not
sufficient Ram) a very long time
So do not click or do nothing (including use of other SW )for a while
Crashes at least for bundled tools and plugin are rare, and usually reported
by popping out error message..if no error messages pop out good chances that
Gimp/the OS is simply too busy to process data and so can't be responsive to
other users input, or do nothing else for a while
Also start Gimp from console in verbose mode may help... in case of apparent
freezing a look to the console output may help to know if gimp is busy to
slowly process a big amount of data or if something wrong happened and waiting
will be only delusive
A extreme case from my experience i used gimp to do some complex mapping
operations (creating 300 additional interpolated layers for a animation) on
a already very heavy image
That totally frozen not only gimp but all the OS for
all the afternoon..anyway i decided to not arrest the apparently frozen PC
before going to sleep
And the morning after i had a nice surprise everything was correctly
.note was a extreme case ,and the result of a wrong procedure..final size of
the SAVED image was absolutely unreasonable (more then 6 GB .and much more
needed to reopen with gimp )
But is just a example to explain that freezing may be only apparent even if
nothing happens for hours
