Celtx, more than most software, needs a connection to the Internet for several important reasons, including formatting and getting tools. We need to make sure that is in place.
First, let's open an empty project. Just click on Film on the Celtx splash page under Project Templates to open one up and it will look like the following screenshot:
Click on Tools, and then click on Options. This gives us a dialog box that those of us who use Firefox should recognize! That's because it's the same as Firefox's, as Celtx uses the Mozilla's software as one of its underlying engines. We want to check the Network options, which are shown in the following screenshot:
If you have a direct connection to the Internet, you're done and in fine shape. If you need a proxy to connect to the Internet, as I do, then you need to enter the information for your proxy server. This will be the same configuration as is in either Firefox, Internet Explorer, Safari, or whatever browser you use to surf the web. It's crucial that Celtx can see the web.
Additional dictionaries are available for the spellchecker. These are needed if you want to, for example, write in more than one language and proof them all. For the basic American English installation, the right dictionary is already in place.
Note
If you seriously want to sell scripts, spellchecking and other proofing is absolutely critical. Nothing will get your script tossed without being read faster than having a script with a bunch of typos in it.
Here's how to add dictionaries, so we can do that all-important spellchecking.
