Adding the ChemDraw Control to a userform in Excel causes the following error:

"Run-time error '28' Out of stack space" error.

If you are doing something similar to the following:
1. Open Excel
2. Click Tools -> Macros -> Visual Basic Editor (or Alt+F11)
3. Click Insert -> UserForm
4. In the Toolbox that appear on the left, right click and select Additional Control... and scroll down to select CS ChemDraw Control (check the box)
5. Now the Chemdraw control (ChemDrawCtl) will appear on the Toolbox. Select the ChemDrawCtl and place it in the UserForm1 in the right.
6. Run this userform by selecting Run -> Run Sub/UserForm

and get a "Run-time error '28' Out of stack space" error. and every time you try to access the userform it says "Path/File access error", the problem has to do with machines that have the Excel forms dll from Office 2000. If you install any Office 2003 component (e.g. Project, Visio, Access, etc.) the forms dll is automatically upgraded and this problem goes away.
