This happen with me one time wend i try to load 2 times the modules... saying something like "modules already loaded" and this small box never go's way.
I've done a little more testing by disabling all the modules and loading them one at a time and here's what I'm getting:
When I try to load dual_iso i get an error that says:
"tcc: error: undefined symbol 'file_prefix_set'
"tcc: error: undefined symbol 'file_prefix_reset'
[E] failed to link modules"
When I try to load file_man I get:
"Load modules...
load: FILE_MAN.MO
Linking..."
And it just stays on that screen and I have to remove the battery to get it to go away.
When I try to load ettr I get locked on the "Scanning modules..." screen and I have to remove the battery to get it to go away.
I can successfully load pic_view but it doesn't seem to function. I have DNG images that I acquired through shooting burst but it still says no image when I try to view them with the pic_view module loaded.
