Rare exception when changing zoom

[Yuriy Chernyshov]

Hello.

I'm using google maps api v3 in this page:
http://software.scanex.ru/ScanMagic/2.7.9/MapGoogle.html

Also, ActiveX component is used to communicate with Desktop Application.

I hooked zoom_changed event with a handler which sends updated zoom value into ActiveX.
Sometimes when I change zoom level too fast (using standard zoom control) I get javascript exception "Invalid argument" at line 1 char 333 in main.js.

What I've done wrong?

Thanks for further help.
Georg.

In Firefox I get the following error continually:

Error: MagicCommunicator.Trace is not a function
Source File: http://software.scanex.ru/ScanMagic/2.7.9/MapGoogle.html
Line: 178

Or should this be a map for Internet Explorer only?

(ActiveX is proprietary MS software, Google's maps are platform
independent.)

Yes, this html is designed to open via CHtmlView (which is embedded IE actually).

I even tried to comment almost all the code - but problem still persists.
