I moved cursor to a folder and pressed the space bar to calculate it's size.
After a few seconds I received the message above.

This might be due to some system call returning error, because on this disk I have filesystem corruption issues.

This is not reproducible in the same instance. If I try to repeat, TC thinks for a moment and stops, w/out displaying any size. However, after restart it was happening again. So I tried to go deeper into the directory structure to identify the smallest one that would show such behaviour, but at some point it stopped happening and I can't reproduce the issue at all.

Also, you can see another bug here - by using regular MessageBoxes, TC mixes own language with the OS one.

That's strange indeed - the floating point error occurs at this line:
if size<maxlongint then begin
fields2_size:=trunc(size);

for some strange reason, one of the files must have reported a large negative size value. I will try to catch it.
