Spell Catcher X 10.4 - Yes
Spell Catcher X 10.4 has been undergoing testing and development with Lion developer builds for many months now, and works fine.
Spell Catcher X 10.4.1 adds support specifically for new-in-Lion features and capabilities. Version 10.4.1 is a free update for Spell Catcher X 10.4 owners. As well, it addresses (as best as is possible) the known issues described below.
There are some known issues with Spell Catcher X 10.4 running on Lion. In general, they are cosmetic only. Others are due to changes in Lion that affect or are applicable to all applications.
- Look Up Window
This was fixed by Apple in Mac OS X 10.7.2.
In Lion, Source Lists (aka “Sidebars”) display either “Show” or “Hide” depending on their collapsed state, rather than a disclosure triangle, when you hover the mouse over such an item. Currently, there is no supported way for applications to specify the actual position of this text - it is calculated automatically.
Spell Catcher X 10.4 displays checkboxes to indicate and toggle the “Use?” and “Sync?” states. The way the Mac OS draws the "Show" and "Hide" text interferes with these checkboxes.
This issue affects other applications and their developers as well. Bug and enhancement reports have been filed with Apple.
- Updating Input Method Components
In Lion, updating (or re-installing) an input method component doesn’t always work as expected. It seems that when Spell Catcher updates or re-installs its input method component, the Mac OS X doesn’t immediately recognize it. Input method applications (64-bit capable) don’t appear to suffer from this problem.
The most reliable work around I’ve found is to Log Out and In again, or to Restart.
Update: Spell Catcher X 10.4.1 includes a reasonably effective work around for this bug.
- Persistent Application State
In Lion, application state is preserved across Log Out/Log In and Restarts by default. Applications have to specifically “opt-out” of this behavior. This means that if Spell Catcher (or any other application) is open when you Log Out or Restart (and “Reopen windows when logging back in” is selected), it will automatically be opened by the Mac OS X. So in Spell Catcher’s case, the usual ways to keep it from launching when you Log In don’t apply on Lion. That is, if the Spell Catcher application is open when you last logged out, by default Lion will open it automatically the next time you are logged in.
Update: Spell Catcher X 10.4.1 addresses this issue.

Remember that Spell Catcher X 10.4 was really only tested on Mac OS X 10.7 (Lion) by a limited team—me (the developer).

Post in our forums, or send us the report by email (Spell Catcher application, Help > Send Feedback by E-Mail).
Spell Catcher X 10.3.7 and earlier - No
Earlier versions of Spell Catcher X aren’t totally compatible with Lion, as numerous changes were made to the way the Input menu works (for all input methods). By the time these changes were discovered, development on Spell Catcher X 10.4 was well underway.
