IE7 bug/feature: iframes not loading (sometimes)?

iframe: now it loads, now it doesn't

[swa66]

Although I cannot seem to be able to create a small sample,
I have trouble with iframes sporadiacally not loading in IE7.

When it didn't load, if you look at the source the

<iframe ....></iframe>

is shown as only the </iframe> part, the rest have become spaces.

I've only been able to have it on real live rather complex pages. I've seen it in php generated pages (and yes, it generates that part always) and in static pages.

Works fine in Firefox & Safari ..., validates etc.

Are you saying that spaces are appearing in the source code or that the space occurs on the page? Either way, it sounds more like an issue with ad-blocking software which is disabling inline frames of certain dimensions.

I'm saying that IE7 kicks out iframes every so often.

I've a page that load a number of identical iframes
near the bottom (floated next to eachother), I've seen it load just a few, I've seen it load none, I've even seen it forget to load regular images on the page.

It does so for different sizes of iframes, sometimes it's consistent in kicking it out, but most cases I've seen a consecutive reloads exibit random failures/success.
changing things to the page (e.g. an added table), can be enough to cause the failure with nearly 100% success rate.

No ad blocker on that machine.

When doing a view source in IE it displays spaces instead of part of the <iframe> tag.

It works fine in IE6, FF, safari.
