save dialogue stuck

[Friedrich F. Grohmann]

I imported one medium sized HyperCard stack (approximately 5500 cards) 
into Rev. A considerable number of handlers had to be rewritten and now I 
am developing the stack further in its new environment. It works very 
nicely apart, alas, from the Chinese stuff but today I won't go into 
that...

What irritates me a little bit is that the "Save ..." screen gets quite 
often stuck. The cursor turns into a hand and no clicking helps to remove 
the window. I have to save again. Both screens will overlap for some time 
and then disappear as expected. What could be the reason for this 
annoying behaviour? How could it be avoided?

Thanks in advance.
