Description
This bug is back in RAD Studio 2007 + Dec2007 Update.
It had apparently been fixed in the initial release of RAD Studio 2007, after first being introduced in Delphi 2007 Update 1.

If the Welcome page is closed* when the IDE is configured to use the classic undocked/non-embedded layout, the IDE crashes if you attempt to open or create more than one project in a single session.

*or disabled entirely by hacking startpageide100.bpl out of the registry.

Steps to Reproduce:
1. Select the "Classic Undocked" desktop layout.

2. Uncheck the "Embedded designer" option (under Tools | Options | Environment Options \ VCL Designer).

3. Close and restart the IDE so the changes take effect.

4. Close the "bds:/default.htm" window (the Welcome page).

5. Click File | New | VCL Forms Application - Delphi for Win32.

6. Click File | New | VCL Forms Application - Delphi for Win32 again.
   Notice that this time, the new project's form doesn't appear on the screen.

7. Click "Search" on the menu bar.

Result:
Access violation at address 20E9DBFC in module 'vclide100.bpl'. Read of address 00000258.

As far as I can tell, there is no way to get the IDE out of this state. It must be closed and restarted.


Note: This isn't limited to creating new projects. The same error occurs if you substitute steps 5 and 6 with File | Open Project.

Text from original report targeting D2007 Update 1, for reference:


This is a newly introduced bug in Delphi 2007 Update 1.
It does *not* exist in the original release of Delphi 2007, or in Delphi 2006.

If the Welcome page is closed* when the IDE is configured to use the classic undocked/non-embedded layout, the IDE will get stuck in an error message loop if you attempt to open or create more than one project in a single session.

This is 100% reproducible on a fresh install of Windows (2000 or Vista) with a fresh install of Delphi 2007 Update 1.

*or disabled entirely by hacking startpageide100.bpl out of the registry.


=== Steps ===

1. Select the "Classic Undocked" desktop layout.

2. Uncheck the "Embedded designer" option (under Tools | Options | Environment Options \ VCL Designer).

3. Close and restart the IDE so the changes take effect.

4. Close the "bds:/default.htm" window (the Welcome page).

5. Click File | New | VCL Forms Application - Delphi for Win32.

6. Click File | New | VCL Forms Application - Delphi for Win32 again.

Error:  "List index out of bounds (0)"
(See Description for the backtrace.)

Clicking OK doesn't help; the message just returns.


Note: This isn't limited to creating new projects. The same error occurs if you substitute steps 7 and 8 with File | Open Project.
