Browser extension button disabled after first use?

I have added a button to IE backed by a COM object using C#. Iam
able to achieve the required functionality on the click of the button.
However, I am unable to click the button again, i.e., my toolbar button

gets disabled and grayed out. I have implemented
IOleCommandTarget::QueryStatus implementation method as follows:

public int QueryStatus(ref Guid pguidCmdGroup, int cCmds, IntPtr
prgCmds, IntPtr pCmdText)
OLECMD ocmd;
bool temp= true;
return 0;

public int Exec(ref Guid pguidCmdGroup, uint nCmdID, uint nCmdExecOpt,
object[] pvaIn, object[] pvaOut)
Speak();//This function works fine;actually the text on the web page

is read out here!
return 0;
Since the button is disabled after first use, iam not able to use it
for any other links from this page.Please somebody giude me where iam

Thanks and Regards,
