Why is it so that adding a file (sdlxliff) to a sdlxliff-project with 4 tabs (Linguee, Total recall table, TM, glossary) opens several new instances of Linguee, glossary and TC-tables? This happens very often and is quite annoying as some of these tabs can't even be closed (mainly Linguee)?
I'm using the most recent version of CT.
Actually, it seems that you are adding a non-CafeTran project file to another project via Project > Add document... This feature works as along as you add another document (e.g a Word document) to a project created in CafeTran. If you wish to add a sdlxliff file in the multi-file project, just add this file to the folder with your sdlxliff files.
In the coming update, CT will display a pop-up message to avoid the doubling of project's resources.
