| Summary | 0000273: Browsers block the attachment popup window | ||||
| Description | Almost all browsers block popup window after adding an image attachment to a forum post so basically one of the main forum functionality is compromised. Exception should be added to a browser in order the popup window displaying question about adding a thumbnail or full size image work properly. | ||||
| Steps To Reproduce | 1) Create new topic 2) Click Attachment 3) Choose file 4) An Attachment popup window displaying message "Would you like the image to be shown full-size?" should be displayed, but it is blocked by most of the browsers. | ||||
| Additional Information | Tested with the latest versions of Firefox, Chrome, Chromium and Internet Explorer. Some other popup windows are not blocked, e.g. existing attacments popup, emoticons... | ||||
| Tags | No tags attached. | ||||

Behavior is the same in version 7.1.3, too. |

The browsers are blocking a popup legitimately caused by a user event (in this case, originating from Flash though). It's a bug in the browsers really. Obviously it would be preferred to work around, but we can't rewrite the UI in a patch release, and the thumb/no-thumb choice is not very important functionality and can still be achieved via Comcode. |

Chris, thank you for the response. The issues exists even if a simple editor is used; in that case, as I can see, Flash is not involved anywhere. Almost all over the system browsers block popup windows. I thought it might be somehow related to cookies or Composr installation folder path but couldn't find the real cause. |

The attachment uploads are done via swfupload, so the actual buttons clicked to choose a file are flash uploads. Ideally browsers would mark events spawning of a clicked foreground Flash applet as user-generated and thus not blocked, but they don't seem to be smart enough. However, the user can always put in an exception if they use the site heavily enough to care about attachment thumbnail control. |
