A bit. I understand that you need the restoring of message reading
dialog (which is quite easy).

In the case of "static" dialog such as message reading dialog, it is no
problem. But if you have opened dialog such as Options property sheet
and you make a lot of changes, then you switch to another application.
Then after a while low memory conditions occur and pRSSreader is killed,
all your changes are lost. Consider we are making only dialog restore,
on the next start of pRSSreader you will end in Options property sheet
but without changes you have made. Storing all changes to the
"persistent session file" might be quite hard and the code can increase
significantly. The question is: Is such kind of restoring neccesary? And
do you know about any application that does such kind of restoring?

Today, I have finished preliminary version of dialog restoring and the
code increment isn't too big. And there is no visible slowdown too. I
think that the most important thing is to restore the message  reading
dialog. Other dialogs are not so important. But if I have the restoring
feature done for one dialog, making the rest of dialogs to restore is a
piece of cake. And there will be quite good restoring in the pRSSreader
for nothing.
