Module development and code questions

I am using a call back function from Hook_menu by associating a URL and the callback function.

When I then go to the URL the page displays the content provided by the callback function correctly but it doesn't display any of the blocks that I have configured for viewing. These blocks however do display on all node pages.

I have reviewed this with other modules like image.module and directory.module and the same thing happens, e.g. if you go to one of the url's defined by the module any configured blocks are not displayed.

Finishing up on a simple-syntax text filter module, something resembling a Textile subset, which seems to be coming together nicely despite my lack of experience with PHP and REGEX and...

One approach a filter I studied took, which I adopted, was to convert all of the \r\n and \n\r and \n characters sent to the filter by the user text area to \r characters, and explode()ing the text into paragraphs on each \r\r.

I am having trouble with the Event Module. I have installed Flexinode , enabled it and it seems to be fine. I installed the Event module according to instructions(the mysql db checks out fine). In Drupal when I click on Admin-Modules to enable it i get only a blank page, no list of modules to enable or config. If I remove the Events folder from the Modules folder every thing is fine. I downloaded and used the Event 4.6.0 tar file and used that.

Getting "Unable to create thumbnail image" error from "+content > image" ... Why?! -Urgent ...

Thanks

Hi.

I'm currently developing a module that enables users to create, manage and deliver application forms with drupal (forms to apply for money and support from different firms). The problem is that these forms have approximately 40 form elements and it needs to look exactly like the paper-version of the application form. It's pretty "advanced" when considering the layout of the elements so I need to design the form in Dreamweaver and user the generated HTML into drupal.

For the version, I'm saying it's 4.7 because I just downloaded and installed today... but it could be 4.6. Either way, what happened just now was... :)
