Hi,
We are using TinyMCE as HTML editor and it is embedded on a html
page. A WebBrowser control is used to display this page in a window
application. I am invoking SetContent method from window to set the
content in tinyMCE. It was perfectly working for a year, however it
start throwing below error since today. It is not happening for all
users only one user encountering this issue inconsistently.

System.AccessViolationException: Attempted to read or write protected
memory. This is often an indication that other memory is corrupt.
at System.Windows.Forms.UnsafeNativeMethods.IDispatch.Invoke(Int32
dispIdMember, Guid& riid, Int32 lcid, Int32 dwFlags, tagDISPPARAMS
pDispParams, Object[] pVarResult, tagEXCEPINFO pExcepInfo, IntPtr[]
pArgErr)
at System.Windows.Forms.HtmlDocument.InvokeScript(String
scriptName, Object[] args)

MorganStanley.ctrls.PEPlus.PEPUI.DataMgmt.TemplateUI.pepTimer1_Tick
(Object sender, EventArgs e) in C:\FAR\pe\PEPlus\Application
\BaseRelease\UI\DataMgmt\TemplateUI.cs:line 791

at System.Windows.Forms.Timer.TimerNativeWindow.WndProc(Message& m)
at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32
msg, IntPtr wparam, IntPtr lparam)
I am not sure why it started throwing exception suddenly. Can we get
rid of this issue by re-installing the .NET Framework 2.0.
Help is highly appriciated.
Thanks,
Nitya

I have only run accross this problem once, and it turned out to be a fault of
the computer, not the program. I would check the computers RAM with a memory
testing program such as MemTest86 (free), or if the computer runs vista, you
can hit F8 while booting and use the recovery tools. It has a built in
memory test application.

This seems the most likely to me since you have not had problems before and
you are only having problems on one computer.

You may want to scan for malware as well (virus/spyware).
