I use macOS 12.6 + Katalon Studio v8.3.0 Please have a look at the following Video [![testcase editor got crazy](https://img.youtube.com/vi/IoUmrLEh40Y/0.jpg)](https://www.youtube.com/watch?v=IoUmrLEh40Y) I will write a step-by-step operations I did and saw. 1. I opened the project 2. I opened a Test Case `Test Cases/juni4/ObjectRepositoryGCTestRunner` 3. I ran the test case. It failed. The failure was expected, not a problem. 4. Katalon Studio’s Console displayed messages, which contain a Java Stacktrace. The Stacktrace included some links to Test Case souce code lines. 5. I clicked a link to `(ObjectRepositoryGC.grooovy:62)` 6. Katalon Studio started a tab of Java Editor where the source code file of `Keywords/com/kazurayam/ks/gc/ObjectRepositoryGC.groovy` is opened in the “Script mode” 7. In the Editor, I scrolled to the top of the source. 8. On the left-hand border of the Editor, I noticed the line numbers 1,2,3,4,… are displayed, which appropriate. No problem. 9. I moved the mouse pointer into the Console tab, and clicked another link to `(ObjectRepositoryGC.groovy:42)`. The Editor displayed the line#42 and its around. Its OK. 10. Again I scrolled the page to the top of the source. 11. I clicked a link to `(ObjectRepositoryGC.grooovy:62)`. 12. I noticed that on the left-hand border the line numbers moved while in the source code pane the line#1 and its following lines are statically displayed. 13. **The line numbers of the left hand border moved as I clicked the links in the stacktrace while the source code pane stayed the same, it didn’t move.** 14. I cliked some line on the Editor pane, and moved the cursor up and down by keyboad 🔼 🔽. **The souce code lines were displayed … (how can I express it in English properly) … garbled; crashed; broken.** 15. I confirmed the source code file wasn’t saved changed at all while it was displayed broken. 16. Please imagine, why I clicked the links displayed in the Console? I was intensively debugging my custome Keyword classes which threw Exceptions somehow. The bug of the Katalon Editor distubed me. 17. I know more bugs of Katalon Studio’s Editor like [this](http://forum.katalon.com/t/test-case-editor-displays-garbled-characters-since-v7-9-0-still-persists-in-v8-x/84915). You can download the [Source code](https://github.com/kazurayam/ObjectRepositoryExtension/archive/refs/tags/TestCaseEditorGoCrazy.zip), unzip it, open the project in your local Katalon Studio. ---
