I have to reload a webpage to make a Flash Object in IE7 WinXP SP3. How can i fix this problem?

Hello:

When I want to navigate a webpage that contains a flash object, the Internet Explorer show the icon that the page contains an error, if I relod the page, the page now doesn't show the error and the Flash objects work well. This occurs recently, some weeks ago, I didn't have that problem. How can I fix this problem?

I'm using Win XP SP3, IE8 and Flash 14.0.0.145

I tried to uninstall the 14 version and installed the 13 version but the problem persists.
