This section of the documentation tries to address a number of common and less common issues you can come across while working with GenomeView.
If your problem is not addressed here, please:

The pop-up message means that GenomeView cannot detect the file format automatically. The BED file format is particularly finicky, because the specification is pretty broad on what's allowed, which in some cases conflicts with other file formats.
For a BED file to be automatically recognized as such, it needs to contain all 12 fields.
You can fix the order in which the tracks appear in the configuration file that you supply to the GenomeView instance.
Add lines of the following type to the configuration file to have the gene, mRNA and CDS annotation tracks near the top.
The higher the weight, the lower the track will be displayed.
Tracks that do not have an explicit weight set in the configuration file, will receive one starting at 1000.
Preloading data in GenomeView can be done in several ways and depends on whether you are using the webstart version or the applet version.
Both methods are explained in detail in the integration manual page.
If you are interested in integrating GenomeView as an editor, check out the editor integration page.
This is due to the high read depth.
By default the maximum depth that reads will be stacked is 50. You can change this behavior in the configuration panel:
File > configuration > short reads
Change the number in the box 'Maximum display depth of stacked reads...' to a higher number. This box is half-way down the screen.
No, the coverage and SNP are in a separate data file.
Instructions to create this file:
There are two recommended file formats depending on your visualization needs:
1) TDF: this file format is the most space efficient and fastests, however, it only has coverage information.
see the TDF section in the link above
The Java support Apple provides is different from other platforms, which makes using Java on a Mac a bit more challenging.
Some things that you can do to improve the situation.
1) Install Java 6 from Oracle.
2) Run Java in a separate process from your web browser.

Right click on the multiple alignment track visualization and there should be a menu that has an item which allows you to reorder ("Rearrange order") them. This can be done by dragging the names of the species up and down in the window that pops up when you click the "Rearrange order" menu item.
The most likely problem is that you accidentally loaded the fasta file AND the fasta.fai file. You do not have to load the index manually, GenomeView will treat is as a separate data source, hence the bed features popping up.
When you only load the fasta file, GenomeView will use the index for fast access, but you won't get the weird additional BED features.
Goto 'File'> 'Configuration' > 'Pile up tracks'
Set the maximum height to whatever you want it to be.
This answer only applies to Firefox 3.6.14 and Firefox 4 beta builds. In this release Mozilla broke support for applets:
This will hopefully be addressed shortly by the Firefox developers, this is outside our control.
