Hello Simon,
I have
Java: openjdk version "17.0.17" 2025-10-21
OpenJDK Runtime Environment Temurin-17.0.17+10 (build 17.0.17+10)
OpenJDK 64-Bit Server VM Temurin-17.0.17+10 (build 17.0.17+10, mixed mode, sharing)
Installer: ZAP_2_17_0_Windows.exe. May try the x32 version since the x64 is the one with the issue.
Thank you,
Gareth Warren
