I am using a German installation of Prime, too, and can confirm the problem. The language may be set to "English" even in a template file, but whenever a new text region is created and I start to type, it automatically switches back to "German" so it must be manually set to "English" again and this has to be done for every single text region created. Very annoying! I see no way to change this behaviour but as I generally found the Prime spell checker less helpful I turned it off by default (and thankfully this is working without having to turn it off for every file individually).
Speaking of language settings and annoyances - I like to have the menus in English and the only way to achieve this is to add "/culture:en-US" to the call of Prime.exe by creating an appropriate shortcut. This unfortunately does not affect the error messages which usually are still in German or quite often a silly mix of German and English.
But the worst is that it only works if you start Prime using the shortcut. Double clicking a Prime file or directly opening a Prime sheet posted here in the forum still would use the German version of Prime. It would be necessary to add "/culture:en-US" at various places in the registry to make it work as it should.
It would be much easier and more reasonable if Prime would use a simple configuration file for setting the language as well.
But it seems that the developers have something against reasonable and usable solutions. This is also shown by such elementary things like scrolling in larger matrices. How this was implemented in Prime is terrible and almost unusable! One often gets the impression that there are no professional developers working, but a few boys who enjoy playfully trying out a few ready-made toolboxes ("Hey, mom! Look what I can do!").
