fixed.

Shane has reported the same error. I can only guess, what the bug is, since I there are not much hints. Although it's true, there are some strange things in floating point and fpc. I have added some bound checks for OI and synedit scrollbars. Does this help?

================ 3. The 'close all' menu item should close the open Project, too. Like in Kylix/Delphi.

For lazarus a project is not neccessarily a program, but rather a session. The project info file .lpi stores all the information to restore the current state, when u restart lazarus or reopen the project. When u really want to close the project, then u don't want sessions. Why that?

================ 4. In the 'remove from project'-Dialog nothing in shown.

Hmm. Seems to work for me. It shows no units, if there is no project unit left except the main source. 'View Units' shows the same but also the main source. Can u send me an example or a hint how to reproduce this? Does Add to project work?

It is not needed. It is either a feature from GTK or we are doing something wrong, but each widget receives the messages. A bit annoying.

Now I can start Lazarus again :)

We need a help system.

A project under laz is the sources plus the project specific settings, like open files, breakpoints, bookmarks, cursors, compiler settings, ... . So, if u switch to another project or restart laz and then reopen the first project, you can just go on. Delphi forgets breakpoints and cursor positions between sessions, which I dislike about it. Since this info is stored in the .lpi file together with the project, you can also take your project to another computer and go on. Under Delphi I often had the thought "where was I?". But reopening an old project under laz and seeing my cursor at the method I last edited, this thought has vanished. This is a feature I don't want to miss.
Closing a project without reopening a new one, would mean, that laz can't store your settings.

fixed.

Hi

Some new Bugs:

================

1. Project Options / Forms: If you send a autocreate forms to the available Forms. The code gets updated correctly, but if you switch the form back to auto, the source isn't updated.

================

2. Can not start LAZARUS (Floating-Point (Invalid Operation)): If I start Lazarus I can see the splash, then only the window-frame of the Sourceeditor, but nothing more :(

   I have looked a bit into the code and I have found the position of
   the error. It is in the function GTKVScrollCB in gtkcallback.inc.
   Perhaps the same can occur in the second scrollbar function!?!
   The Floatingpoint-Exception is generated by a line around 1300. Which is
   PageI := Round(Page_Increment). I have looked, what is in Page_Increment
   and it is a very big number (4.294967296E+09), which looks like
   causing the problem. If I change the round to trunc it works. I don't know,
   if then the result is the wanted? I have such a problem with floating point
   in another program, too. Could it be that there are some bugs in the FPC-Floating
   Point code??
   This is the output while starting:

I test this tomorrow

Session?? What do you mean?

I started Laz created some forms and want to remove these again, but nothing is shown in the dialog. (You must remove the forms, which are created, if you click into the componentpalette (the bug with the Tabs and the icons in the left corner)
