Pandora Directive GOG - Missing subtitles?

I'm running GOG version of Pandora Directive, and I miss some subtitles, for example the first time we leave the office to the stairs:

see (min 26'54'')

When I leave I just hear Tex's voice, but subtitles are missing. This will happen again several times (first time in electronic shop, in the water tank, etc)


Well, I found the solution by myself:

don't open the door by distance an then walk through the door, that may cause the missing subtitle (randomly). INSTEAD walk near the door and THEN use the open button. It works.
